Another Wastegate Rattle Thread - Please read

I recently got an 07 335i under CPO and I believe I'm experiencing the wastegate rattle that has been posted about over and over.

I took the car to the dealer while under warranty (Monday) and they told me that the sound that I was hearing was normal. However upon further reading and driving it doesn't appear to be a normal operating sound. I heard it pretty clearly yesterday while driving around and I wasn't listening for it or anything so I know it's not me just being paranoid.

The warranty expired yesterday and I'm not convinced the car was properly diagnosed on Monday so I want to see what I can work out with BMW and/or this dealership to make sure the problem is properly assessed.

I seem to remember reading a thread that had some reference numbers indicating that programming the car to leave the wastegate open should be the first step and if that doesn't solve the problem them then some of the components if not the entire turbo assembly are to be replaced. I can't seem to find this thread now (although I've seen it multiple times). Does anyone know the thread I'm talking about?

I'm just looking for some help on gathering information so I can talk to the dealer and be as informed as possible and prepared incase they try to tell me it's a non-issue.

Thanks all

The wastegate warranty is covered up to 82k.

Is this the document you were talking about? If not I would still bring this to the dealer.

The turbo warranty has been extended to 82,000 miles/8 years so if your car is under that then you have a lot of backing on your side. I suggest taking it to another dealer and complain to them about the WG rattle and see what they do. If no luck there then get in touch with BMWNA.

My dealer told me the same thing. Called BMWNA and brought it to a different dealership. 3 days later I had new turbos installed. Do this.

I can try to talk to BMWNA but I'm out of the warranty as of yesterday so I feel like I'm going to be screwed into figuring something out with this particular dealership

So is this warranty independent of any other existing warranty like a CPO? I guess that's what I didn't understand

It's a recall driven warranty extension for the wastegate rattle issue by BMW on all cars.

It is not a recall.
